So, am I correct to believe that we need to use plain 'inline' for c99 after gcc 4.4, and 'extern inline' before that? That is, I think I need to write a test that looks like...

#if ((__GNUC__ > 4) || ((__GNUC__ == 4) && (__GNUC_MINOR__ >= 4))) \
&& defined (__STRICT_ANSI__) && (__STRICT_ANSI__ != 0) \
&& defined (__STDC_VERSION__) && (__STDC_VERSION__ >= 199901L)
#define ELIDABLE_INLINE inline
#else
#define ELIDABLE_INLINE extern inline
#endif

I'm not quite sure if I've got that right, though. I don't know if I need to test __STRICT_ANSI__ or not. I'm not sure if I should be testing for gnu99 mode as well as std99 or not. I want to match the exact conditions that are going to be tested to invoke the new standard behaviour; is this going to do it?

In gcc-4.3-20070601, a new problem came up. gcc.dg/cpp/trigraphs.c fails due to problems here in cygwin/newlib <stdio.h>, even with the change suggested above.
